Fourth Macedonian War in the context of "Achaean War"

Greece in the Roman era (Greek: Έλλάς, Latin: Graecia) describes the period of ancient Greece (roughly, the territory of the modern nation-state of Greece) as well as that of the Greek people and the areas they inhabited and ruled historically, from the Roman Republic's conquest of mainland Greece in 146 BC until the division of the Roman Empire in late antiquity. It covers the periods when Greece was dominated first by the Roman Republic and then by the Roman Empire.

In the history of Greece, the Roman era began with the Corinthian defeat in the Battle of Corinth in 146 BC. However, before the Achaean War, the Roman Republic had been steadily gaining control of mainland Greece by defeating the Kingdom of Macedon in a series of conflicts known as the Macedonian Wars. The Fourth Macedonian War ended at the Battle of Pydna in 148 BC with the defeat of the Macedonian royal pretender Andriscus.

Macedonia (Latin: Macedonia; Ancient Greek: Μακεδονία) was a province of ancient Rome, encompassing the territory of the former Antigonid Kingdom of Macedonia, which had been conquered by the Roman Republic in 168 BC at the conclusion of the Third Macedonian War. The province was created in 146 BC, after the Roman general Quintus Caecilius Metellus defeated Andriscus of Macedon, the last self-styled King of Macedonia in the Fourth Macedonian War. The province incorporated the former Kingdom of Macedonia with the addition of Epirus, Thessaly, and parts of Illyria, Paeonia and Thrace.

During the Republican period, the province was of great military significance, as the main bulwark protecting the Aegean region from attacks from the north. The Via Egnatia, which crossed the province from west to east was of great strategic importance, providing the main overland link between Rome and its domains in the Eastern Mediterranean. In this period, campaigns against the Dardani and Scordisci to the north and the Thracians to the east were nearly constant. By the first century BC, the province notionally extended to the Danube.

The Macedonians (Ancient Greek: Μακεδόνες, Makedónes) were an ancient tribe that lived on the alluvial plain around the rivers Haliacmon and lower Axios in the northeastern part of mainland Greece. Essentially an ancient Greek people, they gradually expanded from their homeland along the Haliacmon valley on the northern edge of the Greek world, absorbing or driving out neighbouring non-Greek tribes, primarily Thracian and Illyrian. They spoke Ancient Macedonian, which is usually classified by scholars as a dialect of Northwest Doric Greek, and occasionally as a distinct sister language of Greek or an Aeolic Greek dialect. However, the prestige language of Macedon during the Classical era was Attic Greek, replaced by Koine Greek during the Hellenistic era. Their religious beliefs mirrored those of other Greeks, following the main deities of the Greek pantheon, although the Macedonians continued Archaic burial practices that had ceased in other parts of Greece after the 6th century BC. Aside from the monarchy, the core of Macedonian society was its nobility. Similar to the aristocracy of neighboring Thessaly, their wealth was largely built on herding horses and cattle.

Although composed of various clans, the kingdom of Macedonia, established around the 7th century BC, is mostly associated with the Argead dynasty and the tribe named after it. The dynasty, also known as the Temenid dynasty, was allegedly founded by Perdiccas I, descendant of the legendary Temenus of Argos, while the region of Macedon derived its name from Makedon, a figure of Greek mythology. Traditionally ruled by independent families, the Macedonians seem to have accepted Argead rule by the time of Alexander I (r. 498 – 454 BC). Under Philip II (r. 359 – 336 BC), the Macedonians are credited with numerous military innovations, which enlarged their territory and increased their control over other areas extending into Thrace. This consolidation of territory allowed for the exploits of Alexander the Great (r. 336 – 323 BC), the conquest of the Achaemenid Empire, the establishment of the diadochi successor states, and the inauguration of the Hellenistic period in West Asia, Greece, and the broader Mediterranean world. The Macedonians were eventually conquered by the Roman Republic, which dismantled the Macedonian monarchy at the end of the Third Macedonian War (171–168 BC) and established the Roman province of Macedonia after the Fourth Macedonian War (150–148 BC).

The Battle of Pydna was fought in 148 BC between Rome and the forces of the Macedonian leader Andriscus. The Roman force was led by Quintus Caecilius Metellus, and was victorious. The battle played an important role in deciding the outcome of the Fourth Macedonian War, and saw the annihilation of the last military-political force of Macedon.

The war had begun when the pretender Andriscus defeated Rome's clients in Macedon and crowned himself king, defeating a Roman force sent to stop him and invading parts of Greece. The senate then sent Quintus Caecilius Metellus with another, larger army to stop the pretender; the Roman commander chose to undertake both a land and sea offensive, forcing Andriscus to take a defensive position near Pydna, where Metellus engaged and soundly defeated him.

Andriscus (Ancient Greek: Ἀνδρίσκος, Andrískos; fl. 154/153 BC – 146 BC), also often referenced as Pseudo-Philip, was a Greek pretender who became the last independent king of Macedon in 149 BC as Philip VI (Ancient Greek: Φίλιππος, Philipos), based on his claim of being Philip, a now-obscure son of the last legitimate Macedonian king, Perseus. His reign lasted just one year and was toppled by the Roman Republic during the Fourth Macedonian War.

Ancient sources generally agree that he was originally a fuller from Adramyttium in Aeolis in western Anatolia. Around 153 BC, his ancestry was supposedly revealed to him, upon which he travelled to the court of his claimed uncle, the Seleucid monarch Demetrius I Soter, to request assistance in claiming his throne. Demetrius refused and had him sent to Rome, where he was judged harmless and exiled to a city in Italy; he managed to escape, and after gathering support, primarily from Thrace, he launched an invasion of Macedon, defeating Rome's clients and establishing his rule as king. The Romans naturally reacted militarily, triggering war; after some initial successes, Andriscus was defeated and captured by the praetor Quintus Caecilius Metellus Macedonicus, who subdued Macedon once again.

Quintus Caecilius Metellus Macedonicus (c. 188 BC – 116 BC/115 BC) was a statesman and general of the Roman Republic during the second century BC. He was praetor in 148 BC, consul in 143 BC, the Proconsul of Hispania Citerior in 142 BC and censor in 131 BC. He got his agnomen, Macedonicus, for his victory over the Macedonians in the Fourth Macedonian War.
